“…The stable state refers to the state of the device stabilized in the absence of external stimuli. Compared with mono-stable devices [ 8 , 9 , 10 , 11 , 12 , 13 , 14 ], multi-stable devices can be stabilized in a variety of states (mostly two or three) when there is no external stimulus [ 15 , 16 , 17 , 18 , 19 , 20 ]. Due to the low energy consumption (especially when the device does not need to frequently switch its optical state), multi-stable devices have strong application prospects in energy-saving places [ 21 , 22 , 23 ].…”

Electrically driven multi-stable cholesteric liquid crystals can be used to adjust the transmittance of incident light. Compared with the traditional liquid crystal optical devices, the multi-stable devices only apply an electric field during switching and do not require a continuous electric field to maintain the various optical states of the device. Therefore, the multi-stable devices have low energy consumption and have become a research focus for researchers. However, the multi-stable devices still have shortcomings before practical application, such as contrast, switching time, and mechanical strength. In this article, the latest research progress on electrically driven multi-stable cholesteric liquid crystals is reviewed, including electrically driven multi-stable modes, performance optimization, and applications. Finally, the challenges and opportunities of electrically driven multi-stable cholesteric liquid crystals are discussed in anticipation of contributing to the development of multi-stable liquid crystal devices.
